摘要：
OFDMA (orthogonal frequency division multiple access) has emerged as a promising physical layer technology for 4G wireless networks. Along with the requirement for higher system capacity, how to improve cell edge performance to provide better QoS (quality of service) support has become a pressing issue. Considering the channel characteristic in wireless communication, new interference avoidance based algorithms, which consider both time domain and frequency domains, are proposed to mitigate the influence of frequency selective channel on cell edge user in MIMO-OFDM system. Meanwhile, in order to further improve the system spectral efficiency, an algorithm that integrates beamforming is put forward. Simulation results show that the proposed algorithms can improve the throughput of cell edge user effectively as well as the overall system throughput.
